Abstract
The utility model discloses a block type brake of an elevator. The brake comprises a yoke, at least two groups of solenoids, an armature a friction disk and a spring; the end face of the yoke is machined with at least two concentric coil grooves; the solenoids are disposed in the coil grooves respectively. The brake is designed with double concentric coils, has the advantages of simple structure, and rapid and reliable motion of the armature; can increase the reliability of an equipment, because when one solenoid fails, the other solenoid still works normally.
Description
Technical field
The utility model relates to electric controlled brake device, is specifically related to a kind of elevator block brake.
Background technology
In elevator brake equipment; adopt block brake through regular meeting; the elevator block brake generally adopts unicoil as takeoff output at present; when the elevator block brake moved, monocoil Distribution of Magnetic Field inequality caused armature movement not rapid; the time lag phenomenon is arranged sometimes; when the magnet coil fault, whole elevator all can't use, and reliability is relatively poor.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of magnetic field even, and failure-free elevator block brake is swift in motion.
For achieving the above object, the technical solution of the utility model is: a kind of elevator block brake, comprise yoke, magnet coil, armature, friction lining and spring, be processed with at least two coil grooves on the end face of described yoke, described magnet coil is at least two groups, is embedded at respectively in the described coil groove.
Preferably, described coil groove is a concentric circular groove or along circumference well-distributed circular groove.
Preferably, evenly be processed with at least two blind holes on corresponding of the end face of described yoke or the armature, be equiped with the quiet post that is used to cushion with noise reduction in described blind hole, the length of described quiet post is greater than the degree of depth of described blind hole.
Preferably, described yoke is connected with described elevator bolt, and described bolt is hollow bolt.
Preferably, described bolt also is arranged with the non-conductive sliding sleeve.
Adopt the beneficial effect of the technical program to be: adopt concentric twin coil design, simple in structure, armature movement is reliable rapidly, and when one of them magnet coil fault, other magnet coil still can normal operation, has improved the reliability of equipment.
Description of drawings
Fig. 1 is the scheme drawing of a kind of elevator block brake of the utility model.
Numeral and the represented corresponding component title of letter among the figure:
1. yoke 11. springs 12. quiet post 13. blind holes 2. magnet coils 3. armature
31. friction lining 4. release levers 5. hollow bolts 51. sliding sleeves 6. wheel hubs.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1, as shown in Figure 1, a kind of elevator block brake, comprise yoke 1, magnet coil 2, armature 3, friction lining 31 and spring 11, be processed with two coil grooves on the end face of yoke 1, two coil grooves are concentric circular groove, magnet coil 2 is two groups, be embedded at respectively in the coil groove, evenly be processed with four blind holes 13 on the end face of yoke 1, in blind hole 13, be equiped with the quiet post 12 that is used to cushion with noise reduction, the length of quiet post 12 is greater than the degree of depth of blind hole 13, yoke 1 is connected with elevator bolt, and bolt is a hollow bolt 5, also is arranged with non-conductive sliding sleeve 51 on the hollow bolt 5.
Principle of work is, be installed in the elevator block brake on the drg of elevator hoist with bolt, the output shaft bonded assembly friction lining 31 of its armature 3 is held elevator tightly and is dragged the brake hub 6 that draws motor under the effect of spring 11, when elevator stops, the magnet coil dead electricity of elevator block brake, armature 3 is in initial position under the pressure of spring 11, the friction lining 31 of elevator brake is held elevator tightly and is dragged the wheel hub 6 that draws motor, elevator is braked, when elevator need move, magnet coil 2, yoke generates an electromagnetic field, armature 3 overcomes the application force of spring 11 under the effect in magnetic field, drawing friction sheet 31 unclamps elevator and drags the wheel hub that draws motor, and elevator brings into operation.When maintenance, rotate release lever 4, drive and discharge the axle rotation, discharge axle and become arc surface by the plane in the corresponding surface of armature 3, in the groove that arc surface embedding armature 3 is provided with, thereby with armature 3 lockings, to prevent the drg misoperation, hollow bolt is used to adjust the gap between friction lining 31 and the brake hub 6.
Wherein, quiet post 12 can be two, 6 or more, its material can be rubber, plastics or nylon etc., the effect of hollow bolt 5 and sliding sleeve 51 is when magnet coil 2 dead electricity, but armature 3 at high speed demagnetizations, move rapidlyer, hollow bolt can also reduce electromagnetic consumable, and the armature 3 that can also make the elevator block brake that is provided with of sliding sleeve moves more flexible.
Embodiment 2, and all the other are identical with embodiment 1, and difference is that two coil grooves processing on yoke 1 end face are that magnet coil 2 is two groups, is embedded at respectively in the coil groove along the circular groove of circumference rectangular distribution with respect to the axis symmetry.
In the foregoing description, the concentric circular groove of processing on the end face of yoke 1 or along circumference well-distributed circular groove can be 34 or more, and the magnet coil 2 with respective numbers is embedded at respectively in the coil groove then, to reach concrete designing requirement.
Adopt the beneficial effect of the technical program to be: adopt concentric twin coil design, simple in structure, armature movement is reliable rapidly, and when one of them magnet coil fault, other magnet coil still can normal operation, has improved the reliability of equipment.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
